Strength and magnetism of Mn-Pt nanocomposites
Original language description
Using ab initio electronic structure calculations, we have analysed Mn atoms dissolved in a platinum matrix, forming thus intermetallics MnPt3, MnPt7 and MnPt15 that can be considered as prototypes of natural Mn?Pt nanocomposites. On the whole, manganeseaddition makes the resulting Mn?Pt compound softer but increases its resistance to shape deformation. With increasing Mn content, both tensile and compressive theoretical strength is enhanced. In agreement with experiment, our calculations confirm the antiferromagnetic (AFM) ground state of the MnPt7 structure with spins directions altering along the [100] crystallographic direction (AFM [100]). In addition, we have proposed and studied three prototypes of linear MnPt15 nanocomposites consisting of Mnnanochains in the Pt matrix. Again, AFM [100] ordering was found in the ground state of MnPt15.
